App Engine does not support Python libraries using C/C++ modules. Orange uses (for speed) C/C++ implementation of some algorithms. I do not know the limitations of stackato. What was your problem with Orange and stackato?

Stackato refuses to start the application and returns the above command in the error log. no luck using a capital O or Orange-2.0.1b. strange. are there any other alternatives that would let me run in on the cloud?

Hi!I redeployed the app on Stackato and it works like a charm The guys at Stackato support also confirmed that they tried installing and running a simple orange app and it is compatible. Thank you for the help!
